COTTON QOMPRESSOR.

$PEGIFIGATION forming part of Letters Patent No. 704,998, dated July 15,1902.

Application filed April 25,1902. Serial No. 104,707. (No model.)

To all whom it may concern.-

Be it known that I, FRANK L. WHITE, a citizen of the United States,residing at Pine Bluff, in the county of Jefierson and State ofArkansas, have invented new and useful Improvements inCotton-Compressors, of which the following is a specification.

My invention relates to improvements in cotton-compressorsgand theobject of the same is to construct a device of this character which willgive a very high degree of compression with small expenditure ofsteampower.

The novel construction employed by me in I5 carrying out my invention isfully described in this specification and claimed, and illustrated inthe accompanying drawings, forming a part thereof, in which- Figure 1 isa front elevation of my press with the plunger part way down. Fig. 2 isa longitudinal section of the same with plunger up. Fig. 3 is a sideelevation of the same. Fig. 4 is a detail of the rack-bars and pistonroLike numerals of reference designate like parts in the different viewsof the drawings.

The numeral 1 designates a base for supporting my compressor, and footedthereon v are standards 2, surmounted by pillow-blocks 3o 3.

and bears ears 7 to which are pivoted paralv lel link-bars 8, which areoppositely pivoted to one member 9 of a pair of toggles 9.

' The member 9 is pivoted to aknuckle 10, formed integral with thepillow-blocks 3, by a cross-bolt 3. The other member of each of thepairs of toggles 9 is designated 9 and is pivoted to ears 11, formed ona head 12,

carried by the upper end of'a rack-bar 13,

which extends down and through an aperture in the base 1. A roller 14:is mounted in boxes 15 and bears against the smooth back of the rack-bar13, and a pinion 16 is mounted in boxes 1'? and is located to mesh withthe rack. 13. Brace-rods 18 are conmounted between said guides,

nected to the cross-bolts 3 and to the outer ends of the spindles 14E ofthe roller 14 and of the shaft 19, which carries the pinion 16. Gears 20are keyed on the shaft 19 and mesh 5 5 with rack-bars 21,'mountedinguides 22, supported on the base 1. The racks 21 are connected by across-bar 22, which is connected to a piston-rod 23, which fits acylinder 24, constructed to be connected to some source of steam-power.(Not shown.)

Guides 25, footed on the base 1, engage pins 26, seated in the rack-bar13, and thereby hold the rack in line.

In operation a bale of cotton is placedon the plunger 7, and steam isturned into the cylinder 2 1 and the rack-bar 13 actuated to raise theplunger, through the medium of the toggles 9, to compress the bale. Whenthe plunger has reached its uppermost position, the links 8 and togglemembers 9 are vertical and parallel to the guides 4, while the togglemembers 9 are horizontal and extend at right angles to the reactiveforce on the plunger. By this arrangement the plunger is locked, andthere is no downward thrust on the rackbar 13, all the force beingcarried by the blocks 3.

I do not wish to be limited as to details of construction, as these maybe modifred in many particulars without departing from the spirit of myinvention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is 5 1. In a cotton-compress, the combination ofparallel guides, a head-block mounted intermediate said guides, aplunger slidingly knuckles mountedintermediate said guides, arack-bar, otoggles pivoted to said rack-bar and said knuckles, link-bars pivoted tosaid plunger and to one member of said toggles interme diate the ends ofsaid member, a shaft hearing a pinion located to mesh with said rackbar,a pair of pinions keyed on said shaft, parallel racks meshing with saidpair of pinions and connected by a cross-bar, guides for said racks, anda cylinder provided with a piston connected to said cross-bar, substan-I00 tially as described.

2. In a cotton-compress, the combination of a plunger, a rack-bar, meansfor connecting said plunger and said rack-bar, a pinion engaging saidrack-bar, a roller mounted to bear on said rack to hold it in engagementwith said pinion, gears mounted to turn in unison with said pinion,racks engaging said gears, and a cylinder bearing a piston connected tosaid last-mentioned racks, substantially as described.

. 3. In a compress, the combination with a base, guides mounted on saidbase, a plunger slidingly mounted in said guides, aracka roller keyed onsaid shaft and bearing on the back of said rack, a shaft bearing a gearmeshing with said rack, a rack meshing with said gear, means for drivingsaid rack to operate said plunger, diagonal brace-rods connected to theouter ends of said shafts and to said base, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
